Changing Directsound Acceleration Level/ Searching for a registry key

To change the directsound acceleration level I know that I have to change the acceleration key in HKEY_CURRENT_CONFIG\System\CurrentControlSet\Enum\PCI\..........\DirectSound\Mixer Defaults

However the location of the directsound folder varies from system to system because it is contained in a 'VEN_XXX&DEVXXXXXX...' folder which differs according to the hardware installed.
On my system for example the location fo the key is 'HKEY_CURRENT_CONFIG\System\CurrentControlSet\Enum\PCI\VEN_1102&DEV_0002&SUBSYS_80401102&REV_05\3&61AAA01&0&68\DirectSound\Mixer Defaults\'

I need to find a way of searching for that key within the subbranches of HKEY_CURRENT_CONFIG\System\CurrentControlSet\Enum\PCI\

Thanks in advance.

I don't know whether this is the answer, but if you go through the key : 'HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\PCI' until the key : 'service = sbpci' (or any other unique identifier) appear you then know in which 'VEN_XXX&DEVXXXXXX...' the Acceleration key resides in.

Thanks for that but that still leaves the problem of how to search through a section of the registry for a specific key which I cant do.

Thats not a problem.
Take a look at GetKeyNames and GetValueNames in the helpfile.
